Untreated flax or linen fibres are usually pale golden brown or 'écru'.
They become whiter as a result of washing and particularly by exposure to the
sun when wet. It appears that, in ancient Egypt, fine linen clothing could be
made of flax that had been harvested when still green, and, because of the method
of processing used then, this green colour could be maintained throughout spinning
and weaving. At different periods light brown, very white, and pale green clothing
carried implications for status, as they indicated that the garments were new.
Fresh garments would also have been stiffer, effectively starched, because the
natural pectin in the fibre had not yet been washed out. This stiffness, together
with the volume of woven fabric involved, probably accounts for the sharply
defined triangular fronts in depictions of elite men wearing garments - as on
the late Middle Kingdom stela UC 14417 (see the image below).

This natural starch also enabled the woven linen to be pleated; there are examples
of pleating in surviving garments of the Old Kingdom (2686-2181 BC), and in
depictions of various periods.

Adding colour: pigments and dyes

Flax/linen is a form of cellulose, and is particularly difficult to dye. This
is in contrast to protein fibres deriving from animals, most importantly wool.
The great majority of linen was therefore left without additional colour. One
method was to apply pigment, effectively coating the fibres. Both yellow and
red ochre (iron-rich earths naturally occurring in Egypt) had been used to colour
some textiles found in Old Kingdom burials.

The Egyptian language includes a special word for red cloth - insy. This was
among the cloths offered in the daily offering
ritual before sacred images.

An early true dye, which is effective on linen, is a combination of tannin
from plants and reduced iron contained in certain muds (these must be wet, and
are to be distinguished from the dry ochres mentioned above). This could be
used to colour whole cloths various shades of brown, but in fact most often
occurs as a writing ink for marking linen. Surviving examples date to the Middle
Kingdom (2025-1700 BC) and later; examples in the Petrie Museum are from the
late Third Intermediate Period or Late Period (about 700 BC). Note the corrosion
caused by the iron eating into the linen.

Other true dyes include blue from woad, generally employed for stripes at the
side of tunics in the New Kingdom and later. Madder, a red dye, was used similarly,
but without a mordant until the first millennium BC, and therefore early examples
have faded to a soft pink. A non-fast red dye important in the first millennium
BC was safflower. Safflower combined with a weak iron tannin mixture was used
to colour whole textiles red-brown. These occur as shrouds stretched over wrapped
mummies, and the colour can be compared to the red ochre known from the Old
Kingdom.

Adding colour: beads and jewellery

Colour could be added by other items worn over the plain linen garment. Most
often this would be jewellery such as necklaces and collars, worn by both men
and women.

Occasionally more dramatic examples survive, such as the bead-net dresses of
Old Kingdom dancing-girls

In addition, figural motifs could be composed in multicoloured beadwork: most
surviving examples are from first millennium BC burials, though there are also
fine examples from the tomb of Tutankhamun
(1333-1323 BC).
